Electromagnetic stirrer types
According to the installation positions,the electromagnetic stirrers have the varieties as follows:
. Mold electromagnetic stirrer(M-EMS);
. Mold bottom(foot-roller bottom)electromagnetic stirrer(I-EMS);
. Strand electromagnetic stirrer(S-EMS);
. Final electromagnetic stirrer(F-EMS);
According to the magnetic field form , the electromagnetic stirrers have the varieties as follows :
.Traveling wave magnetic field stirrer solidification final area
.Rotary magnetic field stirrer
.Spiral magnetic field stirrer |

?With the electromagnet stirring ,electromagnetic stirrer can improve steel billets'interior construction and the casting billets'surface quality ,make non-metal inclusions float up from the bottom ,minimize the blowholes and the center looseness and increase equiaxial crytal ratio.
. The different installation positions of electromagnetic stirrer have different metallurgical effect.The main metallurgical effect is improving casting billets'quality.(Table on the right)
